Seminar Advanced Topics in Crytography

Corresponding entry in Aachen Campus, Bonn Basis.

Lecture

Time & Place

Thursday 10⁰⁰- 12⁰⁰, b-it 1.25.

First meeting: Thursday, 28 October 2010, 10⁰⁰, b-it 1.25.

Prerequisites

Basic knowledge of cryptography and fast understanding of mathematical and computer science topics is required.

The topic is not yet determined. Previous instantiations dealt with Fuzzy Coding Theory, Zero-Knowledge, PCP, Ellitpic Curve Theory, ... In any case the topic will try to dig deeper than what you expect in a standard course or seminar.

Well, this semester we decided to focus on...

Mobile Communication Standards.

Sources for mobile standards are

the ETSI documentation service. You may have to register but then downloads are free.
3GPP: Relevant standards.
3GPP2.
ITU,
GSM, UMTS and LTE security specifications.

All of these also care for LTE (long term evolution) or 3.9G, as well as 4G.
